Balancing Agricultural, Urban, and Environmental Water Needs in Water Resources

The Lower Colorado River Authority (LCRA) – San Antonio Water System (SAWS) Water Project is a plan to conserve water, develop groundwater, and capture excess and unused river flows to meet future water needs for two neighboring regions in Texas. Agricultural and other rural water needs would be met on a more reliable basis in the lower Colorado River basin through water conservation, surface water development and limited groundwater production, while up to 150,000 acre-feet per year of surface water would be transferred to the San Antonio area to meet municipal needs.

The project is in its fourth year of detailed studies addressing the environmental, agricultural, socioeconomic, and engineering aspects of the project. The studies are developing river instream flow criteria, river water quality models, bay freshwater inflow criteria, surface water availability models and operating approaches, agricultural conservation models and approaches, groundwater availability models, economic models, and others. Current status and results are provided, including the complex issues related to operation of the project within the regulatory environment.

The Amazon Rainforest is worldwide known for its extraordinary biodiversity and large rivers. The facts speak for themselves. It is the largest tropical forest in the world, covering five million and a half square kilometers in nine countries, including Brazil, which presents 60% of the forest cover. It presents the highest biodiversity among all tropical forests in the world. One in ten known species in the world lives in the Amazon Rainforest. The Amazon basin is also the largest drainage basin in the world....

To investigate the influences of river bend geometry on flow structures, three-dimensional simulations were carried out. The influence of aspect ratio, channel sinuousness and curvature ratio were investigated. Simulation results show that with an increasing of channel aspect ratios, the streamwise variation of flow velocities decreases significantly, which is not the case for the spanwise direction. Simulation results also reveal the significant influence of the curvature ratio on the redistribution of primary...

Transboundary water sharing policy between Pakistan and Afghanistan along with emerging issues over the Transboundary Kabul River have been discussed incorporating long-term hydrological trend analysis, water quality issues and temporal changes in land cover/land use. The annual (1977–2015) mean river flow of 26.32 billion (109) cubic metres (BCM) with a range of 13.77 to 42.2 BCM and standard deviation of 6.026 BCM revealed no significant trend in annual inflow data of the Kabul River. Afghanistan planned...

Studying the carbon balance in surface waters gives information on the annual cycles of photosynthesis and respiration. It also provides insight on the water body's capability to serve as a source or sink for atmospheric CO2, which may be essential in evaluating the effects of climate change. The target of this study was the Vantaanjoki River known to have a significant base flow component, located in a densely populated area in southern Finland. The aims of this study were firstly to study if human induced...
